Fulton Sheen gave a talk called “The Approach of Midnight” in the 1970s, imagining the “clock of life”:
“I want you to picture a great and gigantic clock of life. Here is dawn; here is noon; here is dusk; here is midnight. The clock of life at the very beginning of the day is beginning to extinguish life: feticide, the killing of human persons in the womb. That’s the first stroke of the clock.
Then we come to noon: lives in middle age. We’ve already had this strike: six million Jews burned by Hitler. Life at the beginning, life at noon.
Life in the evening. Now euthanasia is recommended: gerocide, the killing of the old. In fact, three American professors in large universities have recommended the killing off of Bangladesh and India, that the rest of us may survive.
Now, what’s going to happen to a world that takes life at dawn, life at noon, life at dusk? We’re eventually going to come to midnight. The United States and Russia have enough nuclear armaments to drop [the equivalent of] ten tons of TNT on every man, woman, and child in the world. That’s the midnight of necrophilism…
It’s not just life at dawn we’re protecting. It’s life at noon; it’s life at dusk; it’s life at midnight…
Go into the world and tell everyone that you meet: there is a life in the womb!”
A consistent life ethic…
